Proper use of Table 310.15 B(2)(b).

I´m an associate professor in the Instituto Tecnológico de Los Mochis, Mx, and my class is on Electrical Installations. I don't find examples to clarify the use of this table 310.15 B(2)(b) on Ambient temperature Correction factors based on 40°C (104 °F). Would you be so kind to share on this...
